Used as a high-performance silicone emulsion in personal care formulations, providing excellent spreadability and a silky, non-greasy feel on the skin. Commonly found in facial creams, sunscreens, and makeup products due to its ability to stabilize emulsions and enhance product texture. Also imparts water resistance and improves the longevity of cosmetic products on the skin. Its low surface tension allows for uniform film formation, making it ideal for use in antiperspirants and deodorants. Additionally, ST271 is compatible with a wide range of active ingredients, including UV filters and vitamins, supporting its use in advanced skincare applications.
